Thanks a lot for your suggestions. I’ll try to implement this improvements step by step with one of a further version.
Currently you could get a bit more overview by the help of layers. With layers you can group some lines/heaters together on one separate designer page.
To move one line or heater to another layer it´s quite simple. Open the context menu over a line/heater with the right mouse button and click the menu option “Switch to a new Layer”. All involved lines and heater to the selected one will be moved to a new or certain layer.
Did this answer your question? We would be grateful if you provide a brief comment as feedback. It may also help others who may have encountered a similar problem.
